The North Carolina General Assembly passed a law in 2012 allowing the use of continuous alcohol monitoring systems as a condition for pretrial release or probation, to mitigate punishments for impaired driving offenses and to ensure compliance with child custody and visitation orders. These systems, commonly referred to as CAM bracelets, fit around the ankle similar to GPS-tracking ankle monitors that are often used as a condition for bail or probation. CAM bracelets monitor the presence of alcohol through the skin by testing samples of sweat every 30 minutes. Above: SCRAM Continuous Alcohol MonitoringĀ® (SCRAM CAMĀ®)
